Samsung has provided its vision for the future of wearable health devices by unveiling a hardware reference design called Simband. This fitness device concept would be underpinned by a new cloud-based platform called Samsung Architecture for Multimodal Interactions (SAMI).

You might be familiar with password storage services like 1Password or LastPass. They beef up security by letting you create complex passwords that you'll never have to remember. Starting today, Galaxy S5 owners who use LastPass can now use their fingerprints to login to their password vaults.

Move over, fingerprints and iris scans, because a new form of biometric identification may soon be joining you – body odor. According to Spanish scientists, peoples' unique BO signatures remain steady enough over time to allow for an ID accuracy rate of approximately 85 percent.

One of the big selling features of phones like the iPhone 5s is their ability to verify the identification of the user by scanning their fingerprint.

myris is a new iris-scanning identity authentication device that promises to improve online security for its users and eliminate the need to remember the myriad of different passwords required for our different digital accounts.

Samsung's Galaxy S5 could be forthcoming in the next few months, and may feature an iris-scanning security feature, according to one of the company's executives. A new iteration of the Galaxy Gear is also expected.

The Fraunhofer Institute for Integrated Circuits IIS recently paired its fitness monitoring shirt with a smart pedelec bike. The system allows performance data measured from the shirt to control the output of the bike's electric motor.

A lot of people like to monitor their heart rate while exercising, plus they also like listening to music. Usually, doing both involves wearing at least a couple of devices. The new On audio headset, however, plays back music and gathers biometric data ... through the user's ear.
